Question

What is the measure of

Answer 1

Answer:

hi your answer is 61°

Step-by-step explanation:

sum of three sides of triangle is 180.

let the unknown angle r be x

$53 + 48 + x = 180 \\ \\ 111 + x = 180 \\ \\ x = 180 - 111 \\ \\ x = 61$

Answer 2

$\huge\mathfrak{Bonjour!!}$

$\huge\bold\purple{ANSWER:}$

⏩ We know that, the sum of the measures of the 3 angles of a triangle is 180°...

Here, the given angle measures of the ∆ SRT are:- angle S= 53° and angle T= 48°

Let's consider angle R as x

Now,

x + S + T = 180°

→x +53° +48° = 180°

→x + 101° = 180°

→x = 180°-101°= 79° =R

Therefore, the measure of angle R is 79°...
